(mathematics) A regular three-dimensional object in which every cross-section is a circle; the figure described by the revolution of a circle about its diameter [from 14th c.].
A spherical physical object; a globe or ball. [from 14th c.]
(astronomy) The apparent outer limit of space; the edge of the heavens, imagined as a hollow globe within which celestial bodies appear to be embedded. [from 14th c.]
(astronomy) Any of the concentric hollow transparent globes formerly believed to rotate around the Earth, and which carried the heavenly bodies; there were originally believed to be eight, and later nine and ten; friction between them was thought to cause a harmonious sound (the music of the spheres). [from 14th c.]
(mythology) An area of activity for a planet; or by extension, an area of influence for a god, hero etc. [from 14th c.]

“The scientist marveled at the perfect sphericity of the planetarium's gigantic model, accurately representing the celestial bodies in their spherical form.”
“It is no exaggeration at all to say that the reality of human evolution is now as well established as is the sphericity of the earth.”
“That procedure reduces degrees of freedom in proportion to the degree of departure from sphericity and protects against Type I errors.”
“Conversely, in partially miscible or immiscible blends, the noncrystallizable polymer generally disturbs spherulite growth.”
“The crystallization rate, crystalline thickness, and spherulite size affect the thermomechanical properties of PLA articles significantly.”
“They added a clarifying agent such as a dibenzylidene sorbitol acetal derivative, reducing spherulite sizes, which reduces light scattering and maintains clarity.”
“They use unique proprietary spherification technology to smooth HA's traditionally rhomboid molecular structure.”
“While the Cointreau technology did not strike him as novel, Mr. Freeman was curious about the spherification kit the company had put together for bartenders.”
“The printer makes use of a molecular gastronomy technique called spherification to convert liquid to gelatinous globules that resemble caviar or tapioca pearls.”
